Who uses Wattsense?

Wattsense primarily targets commercial building managers wanting to collect and supervise their equipment via a proprietary IoT gateway connected to a cloud. The historical positioning is centered on multi-protocol collection (Modbus, BACnet, LoRaWAN, M-Bus) via their hardware bridge, with a simple cloud dashboard.

The typical audience is more operational than technical — facility managers, commercial building operators, HVAC integrators.

Why consider SensIa vs Wattsense

Wattsense and SensIa share a modern IoT-first DNA but target different use cases:

Functional coverage — Wattsense excels at multi-protocol collection via their gateway. SensIa adds on top a rich analytics layer (3D BIM, industrial ISA-18.2 alarms, AI predictive maintenance) that Wattsense doesn't natively have
Business model — Wattsense bills gateway hardware purchase or rental (€500-1500 depending on model) + per-device subscription. SensIa is 100% SaaS with no imposed hardware, you pick sensors from the open market
Hardware independence — with SensIa, you buy any LoRaWAN / Zigbee / MQTT sensor directly from the manufacturer. No lock-in to a proprietary gateway

Key stack differences

Collection approach. Wattsense pushes a centralized gateway strategy — their box aggregates multi-protocol before pushing to cloud. SensIa is protocol-native at the cloud level: LoRaWAN via your provider's LNS, Zigbee via Z2M on a local Pi, generic MQTT for everything else. No proprietary central box.

Functional domain. Wattsense focuses on supervision (dashboards, alerts). SensIa extends to BIM digital twin (import your IFC, drag-drop sensors in 3D) and AI predictive maintenance (RUL, MTBF, LLM recommendations).

Compliance. SensIa natively integrates ISA-18.2 / EEMUA 191 industrial alarm management standards — rare in the French smart building ecosystem.

Migration plan from Wattsense

If you already deployed Wattsense gateways and want to test SensIa:

MQTT coexistence — Wattsense can export data in MQTT. SensIa subscribes and reads in parallel, you keep Wattsense operational
Pilot on a new building — for your next deployments, test SensIa direct without proprietary gateway. Compare the experience
Progressive switch — when ready, redeploy your existing LoRaWAN sensors on SensIa (your TTN / ChirpStack subscription stays yours, no data migration) and terminate your Wattsense contract at the end of commitment

Who SensIa fits best vs Wattsense

SensIa is the right answer if you want:

Native 3D BIM + ISA-18.2 industrial alarms + predictive AI that Wattsense doesn't offer
No proprietary gateway imposed — you keep freedom to pick sensors
Transparent self-service pricing (Free / €49 / €149 / €399) without personalised quote

Wattsense remains relevant if you have:

A park already equipped with Wattsense gateways, with significant hardware investment
A need centered only on legacy multi-protocol collection (Modbus / BACnet / M-Bus) without advanced analytics
A team preferring a physical hardware box to a cloud-only assembly

Frequently asked questions

What's the positioning difference between SensIa and Wattsense?

Both are modern French smart building players. Wattsense is positioned on **hardware-first collection** via proprietary gateway. SensIa is positioned on **cloud-first analytics** — supervision, BIM digital twin, industrial alarms, predictive AI — without imposed gateway. They're complementary approaches more than strictly competitive: you could imagine a Wattsense gateway + SensIa analytics setup for exotic cases.

Do I need a proprietary SensIa gateway?

No. SensIa is 100% SaaS cloud, no imposed hardware. For LoRaWAN, you use a standard market gateway (RAK7268 at €300 for example) connected to your LNS provider (TTN, Helium, ChirpStack). For Zigbee, a Raspberry Pi with a USB coordinator (~€50). For legacy Modbus, a Raspberry Pi with our bridge OS image.

What real savings vs Wattsense?

The gap mainly comes from hardware (proprietary gateway at €500-1500 with Wattsense, vs standard market gateways at €150-400 with SensIa) and per-device billing. For a commercial building with ~50 sensors, SensIa Pro at €149/month (50 sensors included) vs Wattsense with ~50 devices billed plus gateway. Annual gap can reach 30-50% in favor of SensIa at comparable features.

Do my Wattsense sensors work with SensIa?

If your sensors are standard market models (Dragino, Decentlab, Adeunis, Milesight…) — yes, they're in the 300+ SensIa device profile catalog. You redeclare your sensors on your LNS provider (TTN, ChirpStack) which becomes the cloud collection point, SensIa subscribes, no more dependency on the proprietary Wattsense gateway.
